Zeropad each column to preprare for FFT. 

Expand the length of each column to the power of 2. The value of s in each row is also computed. 
\begin{DoxyParams}{Parameters}
{\em Radon} & matrix of Radon image \\

\end{DoxyParams}

\begin{DoxyRetVals}{Return values}
{\em Radon2} & expaned matrix of Radon image \\
\hline
{\em axis\_\-s} & value of s in each row \\
\hline
\end{DoxyRetVals}
